我有一个函数,从字符串列表中删除标点符号:
def strip_punctuation(input):
x = 0
for word in input:
input[x] = re.sub(r'[^A-Za-z0-9 ]', "", input[x])
x += 1
return input
我最近修改了我的脚本以使用Unicode字符串,所以我可以处理其他非西方字符.当遇到这些特殊字符并且只返回空的Unicode字符串时,此函数会中断.如何从Unicode格式的字符串中可靠地删除标点符号？
拜托,有人可以用下面的代码帮我吗？当我运行它时,日志说:
return method(*args, **kwargs)
File "C:\Users\CG\Documents\udacity\rot13serendipo\main.py", line 51, in post
text = rot13(text)
File "C:\Users\CG\Documents\udacity\rot13serendipo\main.py", line 43, in rot13
return st.translate(tab)
TypeError: character mapping must return integer, None or unicode
INFO 2012-04-28 20:02:26,862 dev_appserver.py:2891] "POST / HTTP/1.1" 500 -
我知道错误必须在rot13()中.但是,当我在IDE中运行此过程时,它正常工作.
这是我的代码:
import webapp2
form= """
<html>
<head>
<title>Unit 2 Rot 13</title>
</head>
<body>
<h2>Enter some text to ROT13:</h2>
<form method="post">
<textarea name="text"
style="height: 100px; width: 400px;"></textarea>
<br>
<input type="submit">
</form>
</body>
</html> """
def rot13(st):
import string
tab1 = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ' …我在Google AppEngine(Python SDK)中有这个代码:
from string import maketrans
intab = u"ÀÁÂÃÄÅàáâãäåÒÓÔÕÖØòóôõöøÈÉÊËèéêëÇçÌÍÎÏìíîïÙÚÛÜùúûüÿÑñ".encode('latin1')
outtab = u"aaaaaaaaaaaaooooooooooooeeeeeeeecciiiiiiiiuuuuuuuuynn".encode('latin1')
logging.info(len(intab))
logging.info(len(outtab))
trantab = maketrans(intab, outtab)
当我在交互式控制台中运行代码时我没有问题,但是当我在GAE中尝试它时,我收到以下错误:
引发ValueError,"maketrans参数必须具有相同的长度"ValueError:maketrans参数必须具有相同的长度INFO 2009-12-03 20:04:02,904 dev_appserver.py:3038]"POST/backendsavenew HTTP/1.1"500 - INFO 2009-12 -03 20:08:37,649 admin.py:112] 106 INFO 2009-12-03 20:08:37,651 admin.py:113] 53 ERROR 2009-12-03 20:08:37,653 init .py:388] maketrans参数必须具有相同的长度
我无法弄清楚为什么它的尺寸增加了一倍.带代码的python文件保存为UTF-8.
在此先感谢您的帮助.

由于翻译行显示错误...帮助我下一步做什么..我正在使用翻译从文件名中删除数字.
